To all whom it may concern:

Be it known that I, ALBERT S. HOWELL,

specification. M I M inventlon relates to devices for cleaning film and more particularlytoan appa-j; 'ratus ada ted to dust and, clean cinemato-.

after it leaves the machine that I fully ap ear, and has its e'ndwallp12 and top and ottomwalls provided-with a-con-n tpurpose.

dent-of thecit of. Chicago, county of Cook, and State'of l ll new and useful Im rovementsin Devices for Cleaning Films, 0 which the followmg 1s a aphic as cut the marginal per'forationstherein.

One of the obg'ectsof my invention is the provision of a fi...m cleanin device thatwlll utilize the advantages 0 a rotary brush cleaner and a pneumatic or-suction' cleaner, so that all dust and minute particles will be removed from the surface of the film and after removal will be drawn away therefrom. Another object of my invention is j the provision of a cleaning device thatmay be satisfactorily operate with a filII1 erforating machlne and whlch may be rea ily attached thereto."Still another object of my invention is the provision of a film cleanin device through which the film may be eas1 y threaded. Further objccts of m invention are the provlsion ofa film cleaning device that is constructed of a minimum number of parts, with a maximum of efliciency; that is easy to manipulate; and is a comparatively ineiepbnsive' accessory to a film perforatin apparatus.

I prefer to accomplish t e divers ob e cts of my invention by substantially the means and in the manner hereinafter fully dc pointed out,

scribed and as more particularly in the claims, reference being ad to the accompanying drawings forming a part of this specification, where1n,-

itwill be observed that my clean shell or casing, one end portion 10 whereof while the'opposite end portion or barrel 11,-

do .vice preferably comprises a suitable hollow I f which communicates and is joined therewith, is substantially ellipticalin ross-section: and is closed atvits outer end by a. transverse, end wall 12. The elliptical porwithin which the hereinafter more tion 11 forms a housi brushes rotate, as wil tinuous elongated slot 13. for-the edgewise into the device and its transit T therethrough. The slot is slightly'widened as at 14, 14, in the central portions of the top i and bottom walls and suitable wipers 15 15, are mounted so as to artially close t ese.

Sai wi era 15 are preferably made of strips of fe t or other simi-v lar soft fibrous material, that are laid par- 4 I allel to each other upon opposite sides of the slot' and are clamped between the leaves of suitable clamps or holders 16, 16, by 1 screws 17 or in any. other suitable manner.

Two bearing bosses 20, 20,- are rovided upon the interior of the wall oft e sleeve 18,'the axes whereof are disposed parallel with each other and in the samehorizontal plane, Suitable rotatable shafts 21, 21, are mounted in said, bearings and are extended beyond both the inner and the. outer ends thereof, the inner ends of said shafts being internally screw-threaded and have the threaded ends of brush indles .22, 22,,
